Stellar evolution is the process by which a star changes over the course of its lifetime and how it can lead to the creation of a new star. Depending on the mass of the star, its lifetime can range from a few million years for the most massive to trillions of years for the least massive, which is considerably longer than the current age of the ...
The diagram also shows considerable evolution through time. The red sequence earlier in the evolution of the universe was more constant in color across magnitudes and the blue cloud was not as uniformly distributed but showed sequence progression. One of five patches of sky covered by the COMBO-17 survey. [4]
Co-existence of purple and green pigment-containing microorganisms in many environments suggests their co-evolution. It is possible that the Early Earth's biosphere was initially dominated by retinal-powered archaeal colonies that absorbed all the green light, leaving the eubacteria that "lived in their shadows" to evolve utilizing the residual ...
In the field of stellar evolution, a blue loop is a stage in the life of an evolved star where it changes from a cool star to a hotter one before cooling again. The name derives from the shape of the evolutionary track on a Hertzsprung–Russell diagram which forms a loop towards the blue (i.e. hotter) side of the diagram, to a place called the ...
Rigel is a blue supergiant star in the constellation of Orion. It has the Bayer designation β Orionis, which is Latinized to Beta Orionis and abbreviated Beta Ori or β Ori. Rigel is the brightest and most massive component – and the eponym – of a star system of at least four stars that appear as a single blue-white point of light to the ...

A Blue Sky animated feature based on the fantasy comic Nimona, from She-Ra and the Princesses of Power creator Noelle Stevenson, was under threat of cancellation, but eventually released last year.
The W51 nebula in Aquila - one of the largest star factories in the Milky Way (August 25, 2020). Star formation is the process by which dense regions within molecular clouds in interstellar space, sometimes referred to as "stellar nurseries" or "star-forming regions", collapse and form stars. [1]
